The purpose of this paper is to investigate the corrosion of the heat‐affected zone (HAZ) and weld zone of austenitic stainless steels that have been welded using two different processes. The corrosion behavior is evaluated in synthetic seawater using the electrochemical polarization technique.

Welded and unwelded UNS S30403 specimens were welded by flux core arc, and gas tungsten arc welding (GTAW) techniques. The test equipment consisted of an electrochemical three‐electrode cell using synthetic seawater as the corrosive medium. The scan rate was 10 mV/s and the potential range was −500‐500 mV vs saturated calomel electrode. The pH for the synthetic seawater was around seven. The electrochemical tests were performed after 1, 2, 3, and, 11 weeks. The metal surface was characterized by examination using an inverted microscope and scanning electron microscopy.

The polarization measurements of the flux core arc welding‐HAZ showed a high corrosion susceptibility, while GTAW‐HAZ presented good corrosion performance.

With the application and correct interpretation of this electrochemical technique, designers, welding engineers, and manufactures can access important information and take correct decisions regarding welding processes to meet corrosion resistance requirements.

The methodology and approach of interpreting the polarization plots used in this research can be applied to study other welding techniques and different welded metals in specific corrosive media, which will be of value to the welding industry.

The unexpected Eurozone Sovereign Debt Crisis (2010–2012) aroused different attempts of interpretation among analysts and practitioners. While some attributed the crisis to a “contagion” effect of the Subprime Mortgages Financial Crisis in the United States (2007–2009), others saw in it an expression of deeper fundamental economic imbalances.

This chapter presents an evaluation of whether there is convergence or divergence in the sectorial international competitiveness of the Eurozone area countries. A Dynamic Panel Data analysis on country-level exports for all Eurozone members for a period that goes from 1993 to 2014 finds significant evidence of international competitiveness convergence in four- out of 10-export sectors, and no significant evidence of divergence in the rest. While that evidence is not consistent with the high expectations generated by monetary integration more than 15 years ago, those four sectors correspond to high value-added economic activities and, in that sense, indicate a more homogeneous productive modernization process is taking place in the area.

Women's empowerment is nothing new; it has been acknowledged as an essential element of eradicating poverty and advancing the economy. However, it remains problematic in most developing countries, such as Afghanistan. This research evaluates women's empowerment experiences by utilising Self-Help Groups (SHGs) as a fundamental development method to empower women economically and socially. This study adopts a qualitative research style, with data mainly acquired from rural areas (Kabul province). The findings indicated that SHG involvement is closely associated with families' socio-economic well-being, meaning that SHG participants are more empowered than those who do not engage or are oblivious to SHGs. SHGs confront various obstacles in Afghanistan, including (but not limited to) erroneous cultural norms, security issues, inadequate financial assistance and poor member participation, all of which influence operations. This study makes important recommendations for promoting and achieving women's integration and active participation in SHGs, including increasing social awareness, support from civil society and the government, laws and regulations that support women, strategies to increase women's economic and social empowerment and linking groups to commercial banks.

By examining the impact of the day of the week during the COVID-19 pandemic and the subsequent economic recession, it is possible to provide insights into market behaviour during volatile times that can be furnished to investors and policymakers for informed decisions.

This study investigates the day-of-the-week effect on the Colombo Stock Exchange (CSE), with particular emphasis on the variations in this effect during the COVID-19 pandemic and the subsequent economic crisis.

The study applies the Exponential Generalised Autoregressive Conditional Heteroskedasticity (EGARCH) model, allowing for the evaluation of asymmetric responses to positive and negative shocks. The data span from January 2006 to December 2022 and are segmented into different periods: the entire sample, war and post-war periods, the COVID-19 pandemic and the economic crisis period, each reflecting distinct market conditions.

The study uncovers a significant day-of-the-week effect on the CSE. Mondays and Tuesdays typically show a negative effect, while Thursdays and Fridays display a positive impact. However, this pattern shifts notably during the COVID-19 pandemic, with all weekdays exhibiting significant positive impact, and varies further across different waves of the pandemic. The economic crisis period also shows unique weekday effects, particularly before and after an important political event.

This paper explores the relationship between foreign direct investments and financial reporting changes via financial development in 12 Latin American countries during the period from 1997 to 2010.

In order to control the possible endogeneity problem, the Generalized Method of Moments (GMM) estimation technique has been conducted using country-level panel data obtained from the World Development Indicators website.

The empirical analyses provide evidence that international accounting standards have a significant effect on foreign direct investments. However, financial development associated with such standards reduces this positive effect. This is an important finding, suggesting that investors are likely to prefer portfolio to direct investments in Latin American financial markets that require or permit the use of international accounting standards.

The conclusions that have been drawn from this study are important for investors, creditors, and regulators. Although international accounting standards appear to affect foreign investments, there could be a lack of adaptation of these standards to specific economic environments due to cultural, educational, and economic factors. Therefore, firms, regulators, professional organizations, and accounting firms should make necessary arrangements so that the benefits of using these standards increase their costs.

The study contributes to the international accounting literature by examining the effects of international accounting standards and financial development on foreign direct investments in Latin America.

Nanotechnology's rapid development worldwide is a significant measure for countries to strengthen the building of energy security. Thus, to empirically investigate the underlying effect of nanotechnology on energy poverty alleviation, the authors of this study assess the impact of nanotechnology on alleviating energy poverty in developing countries.

The paper used panel data for 56 developing countries over the period 2012–2019, by employing dynamic generalised method of moments (GMM) analysis.

The findings showed that the emergence of nanotechnology has a significant trend in increasing energy poverty in developing countries. This suggests that whilst nanotechnology may be a promising solution for addressing energy poverty in certain contexts, nanotechnology may not be the most viable option for reducing poverty in developing countries. The findings have added credence as the findings are robust to the inclusion of alternative energy poverty measures and additional controlled variables.

Although this study results show unpromising outcomes in addressing energy poverty in developing countries, the authors believe that this may be a short-term phenomenon. In the long run, policies and programs must be put in place to support the development and deployment of nanotechnology to reduce energy poverty.

The authors believe this is the first attempt to examine the dynamic influence of nanotechnology development on energy poverty in developing countries. From the standpoint of nanotechnology development, this can help policymakers develop rules and regulations to tackle energy poverty.

This research aims to examine the time-varying behavior of the Weekend, Turn-of-the-Month, January, and Halloween effects in eight foreign exchange rates against the U.S. dollar from the Adaptive Market Hypothesis (AMH) perspective. It also explores whether these anomalies can generate excess returns compared to a buy-and-hold strategy.

Using daily return data from January 2004 to December 2023 in a rolling-window framework, the study employs the Concordance Coefficient test and AR-GARCH models to assess the time-varying behavior of four calendar anomalies. It also assesses the statistical significance of the trading strategies implied by these anomalies using t-tests and applies F-tests for subperiod analysis.

The results reveal a generalized time-varying presence of calendar anomalies in emerging currencies and, to a lesser extent, developed currencies. However, the trading strategies implied by these anomalies generally did not show statistical significance, except for the Turn-of-the-Month effect, which exhibited statistically significant unprofitability.

The study pioneers an analysis of five calendar anomalies across various currencies from the standpoint of the AMH and proposes case-specific explanations for their occurrence. It also examines the potential for the anomalies’ implied trading strategies to generate excess returns compared to a straightforward buy-and-hold strategy. Additionally, the study introduces the recently developed Concordance Coefficient test as a valuable alternative to other non-parametric methods.

The purpose of this paper is to quantitatively examine if varying household consumption activities at different income levels drove CO₂ emissions to different degrees in Mexico from 1990 to 2014.

The paper applied a simple expenditure-CO₂ emissions elasticity model – a top-down approach – using data from consumption-based CO₂ emission inventories and the “Household Income and Expenditure Survey” and assuming a range of 0.7-1.0 elasticity values.

The paper results show a large carbon inequality among income groups in Mexico throughout the period. The household consumption patterns at the highest income levels are related to significantly more total CO₂ emissions (direct + indirect) than the household consumption patterns at the lowest income levels, in absolute terms, per household and per capita. In 2014, for example, the poorest household decile emitted 1.6 tCO₂ per capita on average, while the wealthiest decile reached 8.6 tCO₂ per capita.

The results suggest that it is necessary to rethink the effect of consumption patterns on climate change and the allocation of mitigation responsibilities, thus opening up complementary options for designing mitigation strategies and policies.

The paper represents an alternative approach for studying CO₂ emissions responsibility in Mexico from the demand side, which has been practically absent in previous studies. The paper thereby opens a way for studying and discussing climate change in terms of consumption and equity in the country.
